Persimmon, IgE, Serum
Use
Establishing the diagnosis of an allergy to Persimmon, IgE and defining the allergen responsible for eliciting signs and symptoms. Identifying allergens responsible for allergic response and/or anaphylactic episode to confirm sensitization prior to beginning immunotherapy.
Special Instructions
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients where medical management does not depend upon identification of allergen specificity.
Limitations
False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE (>2500 kU/L). The level of IgE antibodies must be interpreted in the clinical context as some individuals with clinically insignificant sensitivity to allergens may have measurable levels.
